Unlocking BykovTrendAlert: Your Go-To Indicator for MT5 Alerts

Ramdass - Conversion only

The BykovTrend semaphore signal indicator is a game-changer for traders using MetaTrader 5. It comes equipped with alerts, email notifications, and push notifications to keep you informed on the go.

To enhance the functionality of this indicator, several updates have been made to the code, enabling alerts, email messages, and mobile notifications:

New input parameters have been introduced:

input uint NumberofBar=1;// Bar number for the signal
input bool SoundON=true; // Enable alerts
input uint NumberofAlerts=2;// Number of alerts
input bool EMailON=false; // Enable mailing the signal
input bool PushON=false; // Enable sending the signal to mobile devices

Added three new functions at the end of the indicator code: BuySignal(), SellSignal(), and GetStringTimeframe():

string GetStringTimeframe(ENUM_TIMEFRAMES timeframe)
  {
//----
   return(StringSubstr(EnumToString(timeframe),7,-1));
//----
  }

In the OnCalculate() block of the indicator, calls to BuySignal() and SellSignal() functions have been added:

//---     
   BuySignal("BykovTrendAlert", BuyBuffer, rates_total, prev_calculated, close, spread);
   SellSignal("BykovTrendAlert", SellBuffer, rates_total, prev_calculated, close, spread);
//---

In this code, BuyBuffer and SellBuffer are the buffers used to store buy and sell signals. Ensure that empty values in these buffers are set as either zeros or EMPTY_VALUE.

For optimal results, each signal function should be called only once in the OnCalculate() block.

This indicator was initially developed in MQL4 and made its debut in the Code Base on September 28, 2007.
